Custom shoutbox for vBulletin

I am in the process of working on a new project and I need a experienced PHP coder to do a little job for me. I need this shoutbox: Https://[login to view URL] On a vBulletin forum. That shoutbox is on a forumotion website, a free forum platform but obviously I am not using there software, but I really like there shoutbox. I dont no what the best way is, I was thinking you could just customise a pre made vbulletin shoutbox plugin, I dont know.
